Mounting tensions came to a head on Thursday when Sean Hannity took to Twitter to defend executive Bill Shine, who replaced the ousted Roger Ailes as the network’s co-president.

Hannity’s tweet was in response to Gabe Sherman’s story in New York Magazine about Shine’s lack of support from Rupert, Lachlan and James Murdoch of 21-Century Fox, who publicly refused to back Shine in a statement.

Gäbe i pray this is NOT true because if it is, that’s the total end of the FNC as we know it. Done. Best Sean https://t.co/W3BJ2wjzRD

Immediately following the tweet, Hannity addressed the erroneous insertion of the diaeresis in Sherman’s name:

Shine hasn’t been publicly associated with the FNC’s culture of misogyny behind the scenes the way in which Roger Ailes and Bill O’Reilly have.

However, on Tuesday, Shine was one of the names mentioned along with other executives in a class-action lawsuit by 11 former and current employees for racial discrimination in the work place and being dismissive about sexual harassment concerns surrounding Ailes.

He started a hashtag campaign to extend a lifeline to a colleague he brought to FNC in the 90s.

A source close to FNC told Deadline, “Sean is willing to take a bullet for Bill out of loyalty and he knows he’s holding a lot of chits there right now too. If he threatens to leave, and he could, then that really could be the end of the place as we know it.”
